For the AVR based environment and chips there is a good starting point here : www.8051projects.net/files/public/1242392126_2569_FT22383_avr_tutorial.pdf For Arduino based check this ebook here github.com/dboyliao/C_Cpp/blob/master/C%20Programming%20for%20Arduino%20%5BeBook%5D.pdf

are you sure you have connected and properly working RTLSDR Usb dongle to your Raspberry PI? did you use the command rtl_test to check if the dongle is working?

man I do not understand what you are trying to say... are you chatgpt? are you human?

@@justanengineer5599 lol my falt i was trying to ask the usb is there anyway to protect it and can u make a video of a mic and bluetooth jammer with a gameboy case

jammin phones can be easily detected by mobile operator. In fact the cell tower detecys jammimg in seconds and reports it to the operation center in real time. In few minutes the police will knock to your door. In short - I do not recommend

@@justanengineer5599 really?ooouch!thanks a lot for your knowledgement... Also with a low power suply?

Anyway..for learning purpuose only... how could i do?could you recomend to me any tutorial? Is a posible to Jamm only in a 20 meters range? Like your 433-315mhz digispark? I puto those two emisors in paralell and they worked perfectly together

you can buy portable smartphone jammer (it has to cover at least 4 frequencies) from china and test it. But I am telling you its like a looking for trouble

@@justanengineer5599 hehehe thanks..i though any from AliExpress...but cant find them...they are banned? I just need to use for some minutes until drinking and druging people goes from front of my flat...i Live at a Big neigbourhood ..i Will hide It behind some benches...and only play when i need..out from my House ....It is difficult to be discovered by the police i guess..

depends how you use it. If you put it inside your car and switch it on then no one will be able to open your car remotely

seen the video?

just both 2.4GHz jamme + directional antenna combined together with 5.8Ghz jammer + directional antenna. You need to use both sametime

this is old design. the newest which I am showing in latest vids can do up to 5-7 meters depending on the microphone

Yes it is possible with CC1101 and this tool

that will all depend on the range you want to achieve. For 2.4GHz without a power amplifier but with LNB attached and directional antenna I was able to achieve more than 50m range

no but look for my other videos regardin HiLink

I need the details what are the transducers that you used and if they are 25kHz because 40kHz sensors are not good and obviously this is the reason of such small range. Another question is which source code have you used to program Digispark. Do you have an oscilloscope and can you check if you are getting min 50V at the transducers?

I'm using 40kHz transducers because it's difficult to find the 25kHz version in my country. I'm currently using the source code mic_jammer_digispark_ad9833_new_version5.ino. I checked the output on the transducers, and it's about 2.5V.

well if you have only 2.5v on transducers means it is not working at all. Use the code with 40KHz in the name. As far as I can see it is not even driving the transducers into resonance state

I love this song😃

try also different USB port in your PC sometimes helps. Also using external USB hub may help

it has to be cc1101 board

@@justanengineer5599 sir which 433mhz and 315mhz transreceiver is best for this rf cloning project is available in india under 3 to 5 dollars

cc1101 + esp32 = YES. "some RF 433" + esp32 = NO

it has to be a board with cc1101. Others will not work

as far as I remember it was an ordinary 15cm multistrand wire. You can use whip antenna calculator to find exact length

i am justanengineer

thanks for good a word bro. I am just passing some true knowledge not a fake shit

yep, but you need an amplifier and directional antenna.

as long as it is free of charge 😃

super !

and what jamming range are you getting ? :-) I bet it is no match for my device

check my github page. There is one TQP7M9103 / TQP3M9103 dev kit which according to some internet forum gives 1W power when you alter it with proper components : SMD caps 1.2pF 1.5pF and 1.8pF. forum.amsat-dl.org/index.php?thread/304-driver-pa-up-to-1w/&pageNo=4 The forum guy claims it will work in range 1400-2900MHz power with the peak at 2.4GHz BT frequency github.com/mcore1976/rf-jammer/blob/main/TQP3M9103_chinese-reference-board-Mod%202_4GHz-2.jpg github.com/mcore1976/rf-jammer/blob/main/TQP3M9103_chinese-reference-board-Mod%202_4GHz-frequency-characteristics.jpg

yes I will test yagi uda type of antenna with this device to see the difference

@@justanengineer5599 A Yagi-Uda antenna w/ a 20dB LNA would make this ideal for long-range targeted signal jamming.

I just checked with compact 20cm pcb board like yagi uda antenna and it works amazing!!! antenna for 5 usd

@@justanengineer5599 what is the range? Can you make a video of it?

it is 2x more around 50m

A 50w RF power amplifier? From AliExpress?

Będzie w następnym odcinku. Stay tuned! video już w drodze

next time check twice before making a fool of yourself in public

using 4G and 5G jammer is not a good idea. You will be found and fined pretty fast because cell towers have advanced jamming detection and positioning capabilities. If they are using bluetooth speakers there will be a solution for this in my upcoming video.

@@justanengineer5599 you will be detected if you used omnidirectional antenna and blast it for 24hrs, not if you used directional and direct it towards the receiver (target phone)

sure thats why I bought yagi uda micro pcb antenna

yes it has rj11 socket as far as I recall

Yes, router has rj11 port. But no Volte or Voip facility

yes this one is the best

check my github page. everything is there well explained

nope. NRF is a simple chip and not good for such activities. Check comments down below before posting questions like this. There was already diacussion about NRF24L01

Cc1101 works with sub-freq and nRF is for wireless comm with 2.4ghz like WiFi

this cc1101tool device works only with putty terminal. For the airspy you use only RTLSDR dongle and you need Zadig first to be able to use rtlsdr.

Nope. I am just an engineer showing you the weaknesses of your surroundings. I am doing it all for free

@@justanengineer5599 love it, I say “badass” in a respectful way 🙏🏽

​@@justanengineer5599thanks a lot

yes of course and you can buy VCO to jam it as well. My phone was using L1 GPS band therefore I jammed only L1. Check VCO vendor page through my github links

no currently there is no possibility to use it without a mobile phone or a PC. The reason is that there are many options to be set while playing with this device that wouldnt be possible to configure with few hardware switches. You need a screen and a keyboard thats why the PC is used for this

might be

@@justanengineer5599 I just have the exact same module as you and it didn’t really work out, I was thinking maybe the antenna wasn’t connected to the appropriate hole and couldn’t create a strong enough signal, is it possible to Build something with a stronger antenna perhaps? Btw, thank you for your reply!

Yes it is in my latest video about rf jammer. You just need to use VCO for 433M frequency

there is a book titled 1984 which exactly describes what is happening in this shithole now
